Hear-os work wonders for me. I picked up a box of 200 at H-Depot. They are not the genuine Hear-O s but they were so cheap and they are as good. Not as big but shove two in each if you have big ears LOL!! Good thing to have even if you have a quiet bike. The wind noise is more damaging than the exhaust note.

"The wind noise is more damaging than the exhaust note"....exactamundo!!!!!EXCELLENT!...only reason I ever wear plugs(with a stock exhaust anyway).I got some hearos as well...they do work good.

Hey grn how long did you have the pipes on, how many miles? I noticed once mine got around 1k to 1500 they quieted down abit.. It's like they wore in with heat cycles...

They also used to shoot 2 foot flames out the ass end when I throttled her in between shifts.. It stopped doing that too...

I miss that...

ooooOOOOOyaeh!! Me likes the blue machine gun at night@!

I think they were on there around 600 miles or so.They actually sounded quieter at the beginning...then...they began to develop an 'edge' rasp sound.And it seemed at least with them on there..when I shifted with clutch...there was a fraction of a second of what sounded like a miss(not a pop) just before clicking into the next gear...very quick..but it wasn't doing that at first.

If you want quiet pipes that still give good performance yoshi's are the ticket, quietest of any pipes out there I think with the quiet insert in, and a very "smooth" sound.
Brocks pipes are about performance....no quarter given in the sound department. Same with his maps, its about power. Remember guys he's a dragracer at heart making pipes from a racers standpoint. I think if you like the stock sound and driveability, buying a Brocks pipe is a mistake. If you're a racer or power junkie, and don't care about sound or like it loud, its the only choice.
Rook set a perfect example, he has a cannon, which are loud, but he knew that going in and just adjusted to it with earplugs because thats what he wanted. He sounds like he got the right fit for him

You can have an aftermarket pipe with good sound and driveability, it just seems most folks buy aftermarket because they want more noise and power, so the companies oblige. If you've noticed more and more companies are now offering quiet inserts for their pipes....a sign of the changing times maybe?
Aftermarket mods don't have to ruin the driveability of you're bike, just mod it up to the point you want with the mods you want. The 14R is so strong stock I'd just stick a pair of good-looking yoshi slips on it and call it done I ran a pair of beautiful gold-into blue TI scorpion slip-ons on my blue 14 before the turbo, they looked stunning on the bike.....got tons of compliments...I still have them. But they were too loud and droning for my taste, but prolly too quiet for some....who knows?

Pick what fits you're needs

"too loud and droning for my taste",...ya...that pretty much sums it up.And you're right...they are designed really for the strip.By a dragger.Sa'll good though.Reinstalling is not TOTALLY off the table...but for now...my stock pipes are just fine....feeling any kind of 'power loss' going back is really,well...I can't tell....She feels just as strong as before....and the bottom end is back to being smooth again....hell...I didn't spend this cash for her to have a 'different' bike.I love the smoothness of this bird.That's a big point with the engine and all for this one.

Grn14- been reading your post with great interest seeing that I have a Brocks CT single system with PC5 and Brocks Street Map in my garage ready to install on my 2012 Zx14-R. A couple of your comments really got my attention

-"too loud and droning for my taste",...ya...that pretty much sums it up.And you're right...they are designed really for the strip.By a dragger.Sa'll good though.Reinstalling is not TOTALLY off the table...but for now...my stock pipes are just fine....feeling any kind of 'power loss' going back is really,well...I can't tell....She feels just as strong as before....and the bottom end is back to being smooth again....

In one post you mentioned how much you could definitely feel the power increase. In this post you say "she feels just as strong as before." Can you clarify?

When you say they are designed for the drag strip, what characeristic of the pipe and fuel map leads you to state that? Brocks Street map is supposed to NOT turn the bike into a high rpm powered drag bike but keep it nice and lively on the street throughout the rev band.

Another area that is of utmost concern, having installed full exhaust systems on other bikes, and experienced the dreaded low end torque decrease in exchange for high rpm HP is this statement

-"and the bottom end is back to being smooth again"

Are you saying that you felt a loss of low end torque/power or that the power delivery wasn't as smooth? I have heard the oppposite from many who run this system with Brocks Street map, but would love to hear what your meaning was by this comment. Having had a Guhl reflash done on another bike, that could have more to do with what you are feeling down low, (erratic low end perfomance that you mentioned), than than Brocks map or the pipe since your secondaries are opening much earlier with his flash than with the stock ECU. (Not to mean that the Guhl flash I had was bad--to the contrary it was perfect, but opening the flies earlier can produce a bit more of an abrupt delivery of power down low, just as removing the flies will.

As I said I found this to be a very interesting a timely post given my current owenership status of the exact same system. I understand that the sound of pipes are subjective and some are much more tolerant of louder pipes than others but that seemed to be a significant reason for your going back to stock. Yet you seem to almost be on the fence as to whether you are going to go back to the "Brocks system" or not. That's a little confusing given some of the feedback you have given as to what it did to your 14R. It would seem that going back to that system would not be an option or on the table for your consideration.

Lastly let me say that I in a large part really understand what you're saying, I think:) I have had full exhausts and slip on's on about 8 motorcycles over the years. Sometimes it's been great, sometimes it took a LOT of work to get it where I wanted it, sometimes no real noticeable change, and sometimes I regretted it. Typically it all came down to the tune, the map and overall rideability. In the case of the ZX14-R, I have mentioned to friends that it's the first motorcycle I've owned where there wasn't something I was trying to improve upon by going the fuel manager full exhaust route, althought the lure that there is more to be had is strong:) My take is that this bike has near perfect fueling stock and as ugly as those cans are, they make power. The LAST thing I'm interested in doing is making exhaust and fueling changes due to my "can't keep my hands off it" complex:)

Guess I'm looking to hear from you further as to what you felt the primary factors were with your decision to pull the whole system, particularly as it relates to rideability and low end performance.

Thanks

I think Brock Davidson has been mischaracterized, or rather, his exhaust systems have.

When I got my 2008 ZX14 new, it had a marked stumble off idle, and setting the idle up a bit only masked it, didn't solve it. Once I put the exhaust (CT-Duals) and piggy on with Brock's "street" map, that cleared up. She was strong off idle and all the way to just short of redline.

My point is, Brock developed the CT series, and this includes the 2012 versions, for street bikes. And his map is a street map, despite coming from dyno/drag development.

Jagman brings up some good points, above. But he says, of Don Guhl's re-flash for a ZX14R "opening the flies earlier can produce a bit more of an abrupt delivery of power down low, just as removing the flies will."

This is incorrect. I have seen instrumented runs with a digital meter showing RPM, Throttle, % Secondary Opening, and a few other things. Guhl feathers the opening, so it is nowhere near as abrupt as physically removing the flies. Despite the fact he opens them wider, and sooner, he does so in a very progressive, smooth manner.

On the C14, it is near perfect. Changes the bike for the better completely, even with stock exhaust.

Privateer--your comments re: Don's flash are more accurate than mine and what I was trying to express. I recongize the flies were opening around 3K vs 6K on my Connie and you are correct that while there was much more low end it was deliverd in a very linear fashion.
BTW I sent you a PM. Can you check and see if you go it?
Thanks

I did talk about how she felt like a ripper after installing the sytem and map,and Guhl flashed ECU...yes..no doubt about it.The weight difference certainly added to the feeling.With that being said...I can easily recommend the system and his mapping and all.Yes.The street map...which is apparently the same for all the bikes(zx14R's)with these mods is the same across the board...it comes as a package actually...as you know.

I can't speak for anyone else...but anyone getting these systems..whether on a 2012,or other 14 can attest...they will produce a 'faster' response down low...and a strong shot along the powerband when driven agressively.Which is cool.Worth it IMO.HOWEVER....I couldn't handle the sound anymore.It made me feel conspicuous.I didn't want that.And going back to stock...I can see the performance difference easily.And to deal with that noise...to me it just wasn't enough to go with it IMO.IF I liked the growl thing...it'd be very cool.But that's not what I want.If you install...expect a 'quicker' responding throttle thing,and strong acelleration....but you MAY lose a tad of the bottom end driveability....mine was surging.I don't like that.Yours may or may not do that...you can only install and see?I would say....if 'they' get enough comments about the idle and surge thing,they're most likely to(and may even right now)adjust that bottom mapping....IMO...that would be the icing on the cake....pretty sure it's the mapping.I ran the Guhl flash with my stock pipes for several days.It performed quite nicely at those low rpm takeoffs and acellerations along the rpm range.Very similar to the Brock's exhaust performance actually.

I guess you could say...each guy is gonna see a different type of engine behavior as to HOW they add throttle.Everyone with a powerful bike knows there's lots of different ways to take off.I like being able to acellerate quickly,but not like a drag bike guy.And wheelying is not my main fun zone.Lifting the frontend out of corners is not something I try to do...ever.Neither is spinning the rear during cornering.But the zx14R will do those things very easily WITHOUT the Brock's package.Just a bit differently.So that's kinda what I was trying to say about the performance comparo.It's an excellent package for a guy who REALLY intends to rip...I ride agressively sometimes...but not enough to warrant the mods(at this time).

And you Jag are very right...stock...this motorcycle really needs no changes.It doesn't.I wanted to go the exhaust route with my new bike cause I've never had a bike like this one....so I thought it'd be cool to see just what a real professional package would be like on a bike like this.Okay...I've seen.I REALLY liked to weight savings...that could be realized right away....she did feel like a 400 lb bike.Very cool...but getting back on her with the stock stuff back on....I noticed it really wasn't that 'bad' to begin with!

THANK YOU

My 14 runs better with my mods, as long as you know what you're doing and choose good proven mods you're good!
"Bikes run better stock".....?????? Mark you would have to define "RUN"

"I think Brock Davidson has been mischaracterized, or rather, his exhaust systems have. My point is, Brock developed the CT series, and this includes the 2012 versions, for street bikes. And his map is a street map, despite coming from dyno/drag development. "

Actually I was thinking the same thing due to his drag racing history this comes up often, but most everyone I've talked to with the Street Map speak of it's impeccable "street manners.

..I couldn't handle the sound anymore.It made me feel conspicuous.I didn't want that."

-Now that makes sense to me and seems to be a significant factor in your wanting your stock bike back.

they will produce a 'faster' response down low...and a strong shot along the powerband when driven agressively.Which is cool.Worth it IMO.

-And that is music to my ears:)

expect a 'quicker' responding throttle thing,and strong acelleration

-still hearing beautiful music

but you MAY lose a tad of the bottom end driveability....mine was surging.I don't like that.Yours may or may not do that...you can only install and see?

-losing bottom end rideability and surging would not be a tune attribute I would consider a positive either. However, I do think that with the PC5, as you say, that could be tuned out. I'd have to see what kind of "surging" you're talking about though to know if it was an issue or something that needed attention.

.I REALLY liked to weight savings...that could be realized right away....she did feel like a 400 lb bike

All of the talk about weight has no bearing on my decision to swap exhaust. This is a big bike but it has never felt heavy to me...not at slow speed, entering or exiting corners and certainly not at 130 MPH blasts. Maybe I'll be very pleasently surprised by the reduction in weight.

I like being able to acellerate quickly,but not like a drag bike guy

This sounds like you're speaking about needing to run the revs quite a lot higher for brisk takeoffs than you do with the stock pipe and fueling. Are you referring to the sound the pipes emit as you run up through the revs at takeoff or the need to apply more throttle out of the hole?

No...draggers are launching around 3500 or a bit more...to keep the tire hooked up and the nose down...and I think they're doing that with a one tooth up in the rear as well.Can't say for sure,but I would guess the KTRC is in the off position.

You've ridden her some...the bottom response is just a 'tad' 'boggy' at the very beginning of an aggressive takeoff....not once she gets past like 2000....then she really rips(this from a virtual dead stop).Rolling acellerations as you know...with the weight moving...there is no bog at all...just hard thrust.That 'just off idle' thing is ONLY at a standstill,or barely moving.When you ride next...put er in first...start rolling...barely...then punch it.You'll see what I mean....IF you feather that clutch and get the r's up a tad...she's gonna burn rubber really well!With the KTRC "off".The piping and mapping will lessen that 'boggy feeling'...which really is only for a second or so until she's moving out.I would have to say here...it may not be so much mapping,as it may be more of a timing deal.That Guhl flash(mine anyway)will advance the timing a bit.You will notice an increase in that off idle response.I did.Enough to be almost 100% satisfied.It will also cause the powerband performance,passing power...stuff like that to be more peppy.I ran my stock config bike with the Guhl only...there was a marked improvement on the kind of takeoffs I'm talking about.But it didn't go away completely.Also..the idle tended to 'hunt' a tad.Stock...it was 'almost' perfect while idling.Very very little fluctuation stock.The Brock's map...pipe and Guhl ECU really made the idle move around.And that's what it felt like just barely rolling at minimal rpms.I didn't like it.Everything else though(besides the pipe noise)was fine for getting a 'quicker' acceleration gain.But by how much?IDK....enough I guess for almost anyone.It's a good mod.Right now I'm going to run the flashed ECU for a bit again and test it some more.

I should have taken some video of what I'm speaking of with all the mods on there.Trying to explain here is kinda difficult....there are some guys here that know what I mean when I say....lurching or 'pulsing' just off idle while starting to take off with minimal throttle.Just a nice parking lot speed drive...or U-turn speed.Pulling in the clutch WILL cause it to be minimal however.But I didn't like the way it did this without having to feather the clutch for the lowest driving speeds.(I'm talking like...2-5 mph stuff here...not a normal takeoff)

If she's not felt 'heavy' to you,then you will be very happy once you feel how much more moveable around the garage and lifting on a rear stand is.You'll see.Very nice.

There's plenty of 'pros' to this package....and if they get(or somebody does) a smoother bottom mapping going,I may reinstall.The PCV is a great mod for the 14.Lots of good stuff can be done with it.So I'm just waiting till they get some more R&D.For now...she's plenty and I'm very happy with my bike.

Thanks for the response Grn. I do know what you mean actually. I had a Guhl flashed C14 that affected the consistent idle a bit but nothing I paid much attention to.
Sounds like some very slow, off idle fueling manners need to be tweaked and the beauty of having a Fuel Manager of any type, in this case the GrandDaddy of them all, a Power Commander, is that if any of the various maps aren't to one's liking, they are either just a GOOD dyno tune away, OR get the Auto Tune accessory. I honestly can almost say I've had better results running auto tunes on other bikes than I have with custom tunes.

Yep...probably a map tweak would correct it completely.I'm in no rush to ditch my exhaust deal.

The surge is probably coming from the reflash not Brock. That's why one mod at the time is the best way to go about it.I'm not quite sold on reflashes yet, it's a lot of $$ especially if u still need a pc.

How much 4 bike and all goodies ??? Rick = all in $$$$$$$$$$$$$$$$$$$$$$

"The surge is probably coming from the reflash not Brock"......I know as much as some of ya think I don't know anything about anything....the surge is coming from the Brock's mapping.I HAVE an unflashed ECU...stock mapping.With the Brock's mapping(PCV) and the stock ECU...it was there...very much so.With the flashed ECU and no Brock's system,no PCV...the surge is gone.The idle will slightly hunt still because of the flashed timing tables.

Romes!Blashemy!

.the surge is coming from the Brock's mapping.

"The idle will slightly hunt still because of the flashed timing tables."

Let me get this straight. Lots of mods here, so the questions are:

1. This is my original ECU. I had it unflashed and it hunts.
2. I sent the flashed ECU back to Guhl. He sent me one back from some other bike that was getting theirs flashed.
3. I removed the pipe and pig. I just run my original flashed ECU. All that is happening with my flashed only ECU is it, "will slightly hunt."

No...I didn't call Brock.They'll come up with an adjustment here sooner or later....I'm in no hurry.

To Hub...no...no...no.I wrote it completely clear up above.Sorry.

No...I didn't call Brock.They'll come up with an adjustment here sooner or later....I'm in no hurry

Just curioius if you ever spoke to anyone at Brocks. The surging issue with your setup really should not be happening. I would think Brock would want to know about it.

I did post up there...on his member forum.I'm quite sure by now he's read it...and probably has gotten similar buyer responses as well...so I'm not gonna push it with him....I'll just let it work it's way out for now.My friend's BUSA did the same thing with a PCIII and Alienhead system...so it's definitely NOT some new phenomenon.If you can be okay with it...and yours is doing it...then...no prob.As I said...by the time anyone else gets their similar systems....from my posts(and I'm sure others as well) and forward...they MAY have already addressed it and adjusted something.IDK.They load the map at the Brock's place.So they're doing the R&D all the time...and making adjustments as they go.What worked a week ago,may not be still the same now.The mapping is not coming from Dynojet or whomever...it's being put together on their own programs and stuff.
